Can you try by giving 'send as' and 'receive as' permission on the mailbox store for administrator?

Hi, "I run the cmdlet as administrator" First, please make sure the account "administrator" meet the needs of article said. http://technet.microsoft.com/en-us/library/bb266964(EXCHG.80).aspx"Before You Begin" Did you download and install Exchange SP2? Please copy the files "migbase.dll" and "interop.migbase.dll" from the SP2 setup file: setup->serverroles->common to the exchange installed bin directory: c:\program files\Microsoft\Exchange Server\bin and try again. Frank Wang

after copy both file to \bin. I able to run Export-Mailbox cmdlet
